Hi Pascal I am using Amazon EC2 Ubuntu 9.04 jaunty AMI built by Eric Hammond. It was quite quickly installed - finding AMI on AWS, starting, apt-get some current java and that is all. Exchanging BaseX.jars is quite easy, it only might affect related startup scripts, as there are some slight changes in last releases. To run it on server as standalone application you are done quickly, to make it working as a service e requires writting some scripts.
Attached are startup scripts, which were created on my other server (dedicated server, managed by Active24.cz).
start/stop/status: sudo /etc/init.d/basex start
Changing versions of BaseX jar: /opt/basex/version BaseX-6.3.1.jar (trick with modifying link BaseXCurrent.jar)
and scripts client and console
BaseX runs under user basex, there must be related records in /etc/sudoers to let me, as sadmin user, do the tasks (I do not have root access to that server)
Hope, this helps
Jan
PS: I have never played with elasticserver.com as it was not accessible at the time of my attempts. Another topic to investigate (I would think of building stack Ubuntu - python 2.6 or 2.7 - Nagios - boto2.x - BaseX - Java SDK...)

Jan: Would also like an EBS based EC2 AMI available but time constraints as well.... my main issue in that I have not configured an BaseX server as stand alone (wrapped in applications). What do I need on the server (besides the core linux). JRE, Tomcat(?), which baseX jar? Could use elasticserver.com to generate the AMI (so could be used for other virtualization platforms as well). thanks *P

I agree. For better performance, I would recommend EBS based instance as it has better disk performance, not the traditional instance store based on S3. I had in past some issues with performance of PostgreSQL, which was relatively poor.
But I can confirm, that BaseX works on AWS EC2 instance with @root-device="instance-store" @type="m1.small" virtualization="paravirtual". I hope to find time to turn it to EBS based instance store some time.

I think it would be pretty trivial to setup an Amazon EC2 instance running a BaseX server. Probably just need a Linux core with Java installed. This could be shared as a public AMI. best *P

Hi Option to have service like BaseX in the cloud would be very nice. I was dreaming about it too. On the other hand, I understand, that resources, being available at cloud solutions like Google Engine, AWS etc. are of quite different kind, that needed for efficient BaseX. When I see flashing of HD LED on my notebook, when performing bigger operations, I know, porting BaseX to any less disk efficient platform would kill the performance completely.
For now, the only option in the cloud is sort of virtual computer (like AWS EC2 etc.)

PS: Christian - you see, providing great service creates even bigger demand :-).

Hi Min,
I have no idea how much time and effort would have to be spent to support the datastore API. In general, we have spent lots of effort and thoughts into our own storage architecture. It's one of the key factors for the efficiency of BaseX, so I'm not sure if switching to another database backend is such a good idea, not to mention transaction issues, etc. But I might be wrong.

I realize that BaseX can't be used as-is on the Google App Engine. The question I have is how much work would it be to get it up and running
on the
App Engine's datastore API instead of whatever you are using for indexing/storage. There is no access to a filesystem. The datastore
does
have a concept of hierarchical (parent-child) entities. In the
datastore,
the only operations that are supported are: get/put by key, inequality
(<,
, =) filters, and a way to limit results that have a common ancestor
(key). Would this be enough to support BaseX?
Thanks,
Min
